Aims: To recognise ‘Smart’ Materials To recognise uses for ‘Smart’ Materials ‘Chromic’ = Colour ‘USP’ = Unique Selling Point ‘Smart Material’ = A material that responds to a stimulus like heat or light, and then returns to its original state when the stimulus is removed.

Thermochromic Materials Thermochromic ink changes colour according to the temperature of the surface it is bring tested on. Can you think of a use for THERMOCHROMIC inks? Click to see Video

Photochromic Materials Photochromic inks change colour depending on the amount of LIGHT hitting the surface. Can you think of a use for PHOTOCHROMIC inks? Click to see Video

Electrochromic Materials Electrochromic inks are inks that change colour according to varying electrical inputs. The input can be VERY small but the change in colour can be VERY dramatic. Can you think of a use for ELECTROCHROMIC inks? Click to see Video

Hydrochromic Materials Hydrochromic inks change colour according to the amount of water they detect. Can you think of a use for HYDROCHROMIC inks? Click to see video

Phosphorescent Materials Phosphorescent inks are able to absorb light during the day and then glow at night. Can you think of a use for PHOSPHORESCENT inks? Click to see Video
